Cargo Features

[dependencies]
error-chain = { version = "0.12.4", default-features = false, features = ["example_generated", "backtrace"] }
default = backtrace, example_generated

These default features are set whenever error-chain is added without default-features = false somewhere in the dependency tree.

example_generated default

Affects error-chain::example_generated

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality [may be removed in the future](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).
